ACID VOLUME allows the user to enter the volume of the acid
reagent. When the volume is programmed, system automatically
calculates the number of days acid reagent will last.
BASE VOLUME allows the user to enter the volume of the base
reagent. When the volume is programmed, system automatically
calculates the number of days base reagent will last.
It is strongly recommended that each time acid and/or base
reagents are replaced or topped up, a Zero Calibration cycle is
activated using the Start New Reagent Cycle function in Install
New Reagents menu or using the Run Zero Calibration function
in Zero Calibration menu.
TIME (00:00 by default) schedules the Zero & Span Calibration
or Check reactions time (in HR:MIN) for the weekdays if any is
programmed below.
In this menu, Zero and/or Span Calibration reactions and/or
Check reactions are scheduled if programmed on a particular
day of the week. Note that by default, there will be no scheduled
zero and span cycles in the system. See Section
Calibration Menu
for details.
If CAL (CALIBRATION) is programmed, system generates the
zero and span adjust figures which are applied to the reaction
results. If CHECK is programmed, system does not generate
any zero or span adjust figures.
The meaning of the abbreviations used in this menu are as
follows:
- -
No function is programmed.
S
Span reactions only.
Z
Zero reactions only.
ZS
Zero reactions followed by Span reactions.
CAL
Calibration reactions
CHECK Check reactions.
OUTPUT MODE specifies the 4-20mA outputs operation. This
parameter is programmed as: DIRECT (direct mode by default),
BASIC (basic mode), STREAM MUX (stream multiplex mode) or
FULL MUX (full multiplex mode).
In DIRECT mode, each 4-20mA output channel is dedicated to a
specific stream and result type.
In BASIC mode, 4-20mA signals of zero and span
calibration/check reactions are also sent to the 4-20mA channels
programmed as STREAM 1.
In STREAM MUX and FULL MUX modes, specific channels are
dedicated to periodically change their value in steps to indicate
the stream number and result type. This periodic operation
reduces the number of required 4-20mA channels significantly. If
STREAM MUX and FULL MUX modes are required, please
contact manufacturer or distributor for the complete protocols
and the details of required system configuration modifications.
